TASCO Adder
Usage conditions apply
- Description
- This stylus-operated notched band adder has eight columns. A sliding plate atop the machine allows one to adjust the columns for subtraction. A blue-black plastic case holds a metal stylus. Accompanying the instrument are “Instructions for Operating the Pocket Arithmometer.”
- The TASCO pocket arithmometer closely resembles an adder sold by the Gray Arithmometer Company of Ithaca, New York, in the early 20th century. It was distributed by the Morse Chain Company of Ithaca in the 1920s. In 1929, the Morse Chain Company became part of Borg-Warner Corporation. Distribution of the adder soon shifted to the Tavella Sales Company of New York City.
